RE: Building a built-up pattern stab and wing
Thanks Bob.
I thought since there is some down time waiting for glue to set I'd show the jig construction for this wing. This jig is slighlty different from past jigs, typically the jigs leading and trailing edge pieces are a solid straight piece from the table to the rib/leading edge. This jig has a horizontal former/spacer, a spine, that aligns the jig ribs to the elliptical leading edge shape, and then has 1/2" tall longerons top and bottom to prevent the jig ribs twisting when everything is pressing. Usually there’s some racking of the jig with the other jigs but this one is very stable and any future jigs may be built this way. The jigs are cut from 1/8" balsa to make them more durable.
